Meeting will Update Public about Wells G and H Superfund Site in Woburn

(Boston, Mass. – June 22, 2012) – Next week, EPA will hold a Public Meeting to discuss updates at the Wells G&H Superfund Site in Woburn, Mass. EPA recently completed a Vapor Intrusion study at the site, and will be sharing results with the community at 7:00 p.m. on June 28, 2012 at Woburn City Hall.

The Wells G&H Superfund Site contains five source area properties within a 330-acre area in Woburn. Since 1992, various cleanup actions have been implemented. While groundwater treatment systems have been installed which have removed chemicals from over 500 million gallons of groundwater, some concentrations of these chemicals remain in the groundwater.

In January 2011, EPA announced that additional data would be collected in portions of the Wells G&H Superfund Site to evaluate the potential for the contaminants in the groundwater to migrate as vapor into buildings – a process known as vapor intrusion.

EPA has completed the evaluation of data collected at residences and other occupied buildings in the vicinity of the UniFirst, WR GRace and NEP properties. Our conclusions were mainly that vapor intrusion does not pose a health threat inside buildings in the vicinity. EPA technical staff will be available at the meeting on June 28 to provide further information and answer questions from the community.
